    Boric acid, also called hydrogen borate, boracic acid, orthoboric acid and


acidum boricum, is a weak, monobasic Lewis acid of boron, which is often


used as an antiseptic, insecticide, flame retardant, neutron absorber, or


precursor to other chemical compounds. It has the chemical formula H3BO3


(sometimes written B(OH)3), and exists in the form of colorless crystals or a


white powder that dissolves in water. When occurring as a mineral, it is called




    Boric acid, or sassolite, is found mainly in its free state in some volcanic


districts, for example, in the Italian region of Tuscany, the Lipari Islands and


the US state of Nevada. In these volcanic settings it issues, mixed with steam,


from fissures in the ground. It is also found as a constituent of many


naturally occurring minerals – borax, boracite, ulexite (boronatrocalcite) and


colemanite. Boric acid and its salts are found in seawater. It is also found in


plants, including almost all fruits.


Boric acid was first prepared by Wilhelm Homberg (1652–1715) from borax,


by the action of mineral acids, and was given the name sal sedativum


Hombergi ("sedative salt of Homberg"). However borates, including boric


acid, have been used since the time of the ancient Greeks for cleaning,


preserving food, and other activities.
